Hardy Geraniums

Hardy geraniums (also known as cranesbill) add instant charm to any border thanks to their purple, pink, and white flowers—yet there is nothing dainty about these tough-as-nails perennials. Unlike the geraniums that fill your containers, this variety forms dense mounds that spread quickly to suppress the weeds and form a soft edge that lasts until the first frost. Hardy geraniums also require minimal upkeep (light pruning after their first major bloom), are deer- and rabbit-resistant, and attract bees.

Rosemary

Rosemary not only makes a valuable addition to your herb garden but is also a fragrant edging plant in sunny areas of your garden. The dense, needle-like foliage of upright varieties like Arp and Tuscan Blue can be trimmed to create a more formal hedge, whereas creeping types like Prostratus and Santa Barbara work nicely as ground cover near pathways. Be ready to trim and harvest your rosemary regularly, though, as it can grow quickly and lose its shape.

With all the sizes, shapes, textures, and colors of dahlias, it might be hard to pick just one to accent your border garden. Go for a mix of bulbs for multiple styles of blooms. Dahlias behave like perennials in warmer regions but annuals in cooler climates. In Zones 1–7, overwinter by carefully digging up the tubers in the fall and storing them in a cool, dark place in slightly damp peat moss or sawdust.
